Thursday Dish

Siobhan Magnus was booted from "American Idol" last night, bringing the contestant pool to five.  Last night's show included live performances from Rascal Flats, Shakira and Lady Antabelm as well. Next week the remaining five contestants will take on the music of Frank Sanatra. Representatives for Usher are dening rumors that he is engaged to Grace Megual.  They say the rumors are false. Stay tuned for more as it develops. In other Usher news, his protoge, Justin Bieber, has fallen from the top spot on the charts, although he's still causing  histeria everywhere he goes. Fans of singer Trey Songz will be happy to know that the singer is embarking on a headlining tour beginning in July. No dates have been announced as of yet.  For fans of the "Scream" franchise a fourth installment is in the works. It reunites the previous writer, Kevin Williamson, director Wes Craven and actors Neve Campbell, Courteney Cox and David Arquette. The film is slated for a April 15, 2011 release.  Be sure to catch "Lisa Raye: The Real McCoy" on TV One tonight at 9pm. Episodes of "CSI" and "Fringe" air tonight as well. On the tube: "Bones" on Fox, "Survivor: Heroes Vs Villians" on CBS, "Flashforward" on ABC and "Community" on NBC. Happy Thursday!
